Summary
Palatal plane inclination shows a significant negative correlation with skeletal malocclusions. This suggests that palatal plane inclination is not a primary driver of vertical growth patterns, indicating multifactorial influences.
Area of Science:
- Dentistry
- Orthodontics
- Cephalometrics
Background:
- Skeletal discrepancies in vertical facial dimensions contribute to long or short face syndromes.
- Palatal plane inclination is considered a potential factor influencing vertical growth patterns.
Purpose of the Study:
- To investigate the correlation between palatal plane inclination and mandibular plane angle in different skeletal classes.
- To determine the contribution of palatal plane inclination to vertical skeletal discrepancies.
Main Methods:
- Analysis of 15 lateral cephalograms (5 each of skeletal Class I, II, and III).
- Measurement of palatal plane inclination and mandibular plane angle using FACAD software.
- Statistical analysis using Pearson's correlation test.
Main Results:
- A statistically significant negative correlation was found between palatal plane inclination and skeletal malocclusions (p=0.011).
- The study identified a significant relationship between the measured cephalometric variables.
Conclusions:
- Palatal plane inclination is not a major determinant of the vertical growth pattern.
- Vertical skeletal discrepancies are likely influenced by multiple factors beyond palatal plane inclination.

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

01:27Cranial Bones: Lateral View
3.0K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:27Growth of Cartilage and Bone Tissue
3.6K
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

01:22Sutures of the Skull
8.1K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
